| 中文摘要:目的 建立同时测定复方酮康唑软膏中酮康唑、莫匹罗星和糠酸莫米松含量的方法。方法 采用反相高效液相色谱法，色谱柱为Intersil ODS-3（250 mm×4.6 mm，5 μm），流动相为甲醇-pH5.5磷酸盐缓冲液（65∶35），柱温45 ℃，流速1.0 ml/min，检测波长248 nm。结果 方法学验证表明，酮康唑、莫匹罗星和糠酸莫米松3种成分线性关系良好（r≥0.9995），日内日间精密度均小于3.0%，回收率在90%～108%之间，稳定性和重复性的RSD均小于3.0%，符合方法学要求。按照新建立的方法测定了3个批次样品中三组分的含量，结果符合要求。结论 该方法简便可靠，可为复方酮康唑软膏的质量控制提供依据，也为其质量标准研究奠定了基础。 |

| Abstract:Objective To establish a RP-HPLC method for determination of ketoconazole, mupirocin and mometasone furoate in compound ketoconazole ointment.Methods RP-HPLC was conducted on a Intersil ODS-3 column (250 mm×4.6 mm, 5 μm), with methanol-PBS with pH 5.5 (65:35) as the mobile phase and the column temperature was 45 ℃. The flow rate was 1.0 ml/min, and the detection wavelength was 248 nm.Results The methodological verification showed that ketoconazole, mupirocin and mometasone furoate had a good linearity (r≥0.9995). The inter/intra-day precisions were less than 3.0%, The recovery rates were between 90% and 108%. The stability and repeatability of RSD were also less than 3.0%, which met the requirements of method validation. The contents of the three components in three batches were determined by the new method.Conclusion The method is simple and reliable. It can provide a basis for the quality control of compound ketoconazole ointment and lay a foundation for its quality standard research. |
